SPECIFICATION forming part 0f Letters Patent N0. 660,027, dated October16, 1900. Application iiled April 25, 1900. Serial No. 14,335. (Nomodel.)

To n/ZZ wiz/mn, t may] concern:

Beit known that JosIAH K. PRocToR, a citizen of the United States,residingin Philadelphia, Pennsylvania, have invented certainImprovements in Conveyer-Belts, of which the following is aspecification.

The main object of myinvention is to prevent the rapid wearing away ofthe edges or selvages of wire belts and the guides therefor.

A further object of the invention is to prevent the buckling of the wirebelt, as fully described hereinafter.

My invention is particularly adapted for use in endless-belt driers fortobacco and other material in which a perforated belt is used.

In the accompanying drawings, Figure l is a plan View of sufficient of abelt to illustrate my invention. Fig. 2 is a sectional View of Fig. l.Fig. 3 is aperspective View of a portion of one edge of the belt. Fig. 4is a perspective View showing the method of applying the edging to thebelt. Fig. 5 is a View showing the edging applied to a different styleof belt from that shown in Fig. 1.

The belt shown in Figs. l to 4,-inclusive, is a very acceptable belt foruse in drying-machines or in machines using an endless perforated belt,as it is pliable, the sections being linked together, so that the beltwill readily pass around the drums and rolls; but belts of this style,as shown in Figs. 3 and 4, have very rough edges where the one wiresection is turned over and clenched to an adjoining wire section. Thesebelts A travel within grooves I) in the framework B of the machine. Theframework is generally made of wood, as Wood is preferable in drying andsteaming machines. It will be readily seen that the belt cannot runevenly through guides without coming in contact with the verticalportions of the guides at different points throughout the length of themachine, and consequently the rough edges of the belt scrape thewoodwork and in time form splinters, which interfere with the smoothrunning of the belt and in some instances cause the belt to buckle andbreak.

By my inventionl am enabled to use the form of belt shown in Figs. l to4, inclusive, with good results and make a very smoothrunning andlasting belt. This is accomplished by attaching to each edge of thebelir an edging D, this edging consisting of a body-section CZ, in whichis a iilling e of some suitable fabric. A line of stitches t' attach theiilling to the edging, and a line of stitches t form a pocket for thisfilling and form two flaps d d', which extend one on one side of thewire and the other on the opposite side, as shown in Fig. 4. When theedging is in place, the iiaps are secured to the wire by stitches 2 Theedging is preferably made of duck or some suitable material that willwithstand wear, and the filling e is also made of material that willwithstand wear, so that the surface that rests within the groove in theframework of the machine is smooth, as the edges of the belt areprotected by the edging D, and very little wear will take place, as thebelt cannot abrade the walls of the grooves. It will be seen from Fig. 2that the filled body-section d is of the same thickness as the mainportion of the edging, the flaps, as well as the body-section, bearingupon the guides. Before the edging need be discarded and a new edgingsubstituted a portion of the edging can be worn away. A new edging canbe substituted for the old onebysim'ply loosening the stitches i2 t3;but I have found by actual use that there is very little Wear upon thebelt, and the belt will last much longer than those now used.

Fig. 5 simply shows my improved edging applied to a sqnaremesh Wirebelt. The edges of this belt are rough, although not as rough as theedges of the belt shown in Figs. l to 4; but this belt' will not passaround small rollers as readily as the belt mentioned above.

It will be understood that I do not limit myself, however, to any formof metallic perforated belt, as the edges of the belt Will wear awayrapidly, and the rough edges of the belt will cut the walls of thegrooves when made of material such as wood, without the belt is providedwith my improved edging.

I claim as my inventionl. The combination of a wire belt, an edgingconsisting of a filled body-section el, iiaps d on each side of the beltand secured to the 10o beit by stitching, the said filled body-sectionbeing of the same thickness as the main poi-- tion of the edging, sothat the bearing Will be upon the aps as Well -as /upon thebody-seetion, substantially as described.

2. The combination Aoi? a Wire belt, an edging consisting of a filledbody-section and flaps 'on each side of the beit secured thereto byStitching, and a, row of stitches passing Jos. H. KLEIN.
